and additionally represent arbitrary O'Caml values.
It is essential that the same data managers are passed as at the time when the hash table was initialized.
For example, to get a hash table from int to string, use
manage Netshm_data.int_manager Netshm_data.string_manager lm sd val add : ('a, 'b) t -> 'a -> 'b -> unitadd tbl key value: Adds the binding of key to value to the
table. Previous bindings are not removed, but simply hidden.val find : ('a, 'b) t -> 'a -> 'bfind tbl key: Finds the current binding of key in tbl or
raises Not_found if no such binding exists.val find_all : ('a, 'b) t -> 'a -> 'b listfind_all tbl key returns the list of all data
associated with key in tbl.
The current binding is returned first, then the previous
bindings, in reverse order of introduction in the table.val mem : ('a, 'b) t -> 'a -> boolmem tbl key checks if key is bound in tbl.val remove : ('a, 'b) t -> 'a -> unitremove tbl key removes the current binding of key in tbl,
restoring the previous binding if it exists.
It does nothing if key is not bound in tbl.val replace : ('a, 'b) t -> 'a -> 'b -> unitreplace tbl key value replaces the current binding of key
in tbl by a binding of key to value. If key is unbound in tbl,
a binding of key to value is added to tbl.val iter : ('a -> 'b -> unit) -> ('a, 'b) t -> unititer f tbl applies f to all bindings in table tbl.
f receives the key as first argument, and the associated value
as second argument. Each binding is presented exactly once to f.
The order in which the bindings are passed to f is unspecified.
However, if the table contains several bindings for the same key,
they are passed to f in reverse order of introduction, that is,
the most recent binding is passed first.
While the iteration is in progress, the table is locked.
That means you cannot modify it during the iteration.
val iter_keys : ('a -> unit) -> ('a, 'b) t -> unititer_keys f tbl applies f to all keys in table tbl. If there
are several bindings for a key, f is only called once.
While the iteration is in progress, the table is locked.
That means you cannot modify it during the iteration.
val fold : ('a -> 'b -> 'c -> 'c) -> ('a, 'b) t -> 'c -> 'cfold f tbl init computes
(f kN dN ... (f k1 d1 init)...),
where k1 ... kN are the keys of all bindings in tbl,
and d1 ... dN are the associated values.
Each binding is presented exactly once to f.
The order in which the bindings are passed to f is unspecified.
However, if the table contains several bindings for the same key,
they are passed to f in reverse order of introduction, that is,
the most recent binding is passed first.
While the iteration is in progress, the table is locked.
That means you cannot modify it during the iteration.
val length : ('a, 'b) t -> intlength tbl returns the number of bindings in tbl.
Multiple bindings are counted multiply, so length
gives the number of times iter calls its first argument.val shm_table : ('a, 'b) t -> Netshm.shm_table
